Bakery owner and pastry chef Megan Rountree of Grapevine Main Street's Legacy Cakes was the grand prize winner on the May 20 episode of "Winner Cake All." The Food Network's competition series is hosted by chef Giada De Laurentiis and has bakers from around the country compete in elimination settings while creating a themed cake display.

Rountree and her baking assistant, Rachelle Dempsey, were flown to Los Angeles and took home the $10,000 prize after competing in two elimination rounds against three other cake-baking teams. They also had their cake served at the client's party.

"I think we just did a good job at listening to exactly what the client wanted as far as design," Rountree said. "They wanted to go really kind of glam and chic for their baby shower, with the trendy greens and foliage that’s in right now."

Rountree and Dempsey came through the first elimination round with a gender reveal cake topper, featuring a white chocolate rattle filled with colored sprinkles that would reveal the gender of the baby when the rattle was smashed.

Dempsey said while she and Rountree had an hour to put together the cake topper, they had five hours to complete the themed cake challenge.

"You’re trying to familiarize yourself with a strange kitchen and find what you need pretty quickly and start doing the project they give you, and go as fast as you can," Dempsey said.

She and Rountree were named the winners of the contest with their themed baby shower cake.

"We had four palm trees coming up out of the base fort that we had built. And we a had a tier on top of that which had a watercolor effect to look like a pool, and then we had a stuffed teddy bear in a pool float with his little bottle sitting on top of the water tier," Dempsey said. "It was actually a baby shower, so they wanted some baby elements, but they wanted a chic, LA pool party vibe."

The cake was flavored with a lime and a mint rum soak and topped with blackberry buttercream.

This is not the first time Rountree has been on a TV show. In 2010, she was on TLC's "Cake Boss: Next Great Baker." She came in second overall.

She said she plans to continue working at her shop, located at 120 S. Main St., Ste. 20.

"We’ve been here since 2010 so we’re hoping to just continue with that and just continue creating some really fun, custom stuff for local people," she said.
